“atof” function: In C++, the predefined function “atof” is used to convert a string value into a double-precision floating point value; it passes a string literal or character array as an argument and it converts the received value into a double type value; it takes only one parameter as an argument. If the argument value contains nonconvertible contents combined with the integer value then the values will be ignored while converting. In same way, the function will return “0” when the values can’t be able to convert into double data type. Syntax: Syntax for the “atof” function is as follows: double atof (const char* n); In the above statement, “double” represents the return type of the function. “atof” represents the name of the function. “const char*” represents the data type of the passing argument. “n” is a string variable which is required to be converted. Example: The example for the “atof” function is as follows: //change the string literal to a double value. double n = atof ("1258.11E-14 "); In the above line, the string literal “1258.11E-14” is passed as an argument to “atof” and it returns the converted value that is “1.25811e-11”.

Make the following game user friendly with GUI, with some simple graphics. The GUI should be in another seperate class, with some ImageIcon, and Game class should be added into the pane. The following code works as this: The objective of the player is to escape from this labyrinth. The player starts at the bottom left corner of the labyrinth. He has to get to the top right corner of the labyrinth as fast he can, avoiding a meeting with the evil dragon. The player can move only in four directions: left, right, up or down. There are several escape paths in all labyrinths. The player’s character should be able to moved with the well known WASD keyboard buttons. If the dragon gets to a neighboring field of the player, then the player dies. Because it is dark in the labyrinth, the player can see only the neighboring fields at a distance of 3 units.

Program Plan Intro

“atof” function:

In C++, the predefined function “atof” is used to convert a string value into a double-precision floating point value; it passes a string literal or character array as an argument and it converts the received value into a double type value; it takes only one parameter as an argument.

If the argument value contains nonconvertible contents combined with the integer value then the values will be ignored while converting.

In same way, the function will return “0” when the values can’t be able to convert into double data type.

Syntax:

Syntax for the “atof” function is as follows:

double atof (const char* n);

In the above statement,

“double” represents the return type of the function.

“atof” represents the name of the function.

“const char*” represents the data type of the passing argument.

“n” is a string variable which is required to be converted.

Example:

The example for the “atof” function is as follows:

//change the string literal to a double value.

double n = atof ("1258.11E-14 ");

In the above line, the string literal “1258.11E-14” is passed as an argument to “atof” and it returns the converted value that is “1.25811e-11”.

A cylinder of diameter 10 cm rotates concentrically inside another hollow cylinder of inner diameter 10.1 cm. Both cylinders are 20 cm long and stand with their axis vertical. The annular space is filled with oil. If a torque of 100 kg cm is required to rotate the inner cylinder at 100 rpm, determine the viscosity of oil. Ans. μ= 29.82poise
